CLOSING MEANS FOR JARS AND OTHER. VESSELS,

over the top of the lid and having down wardly-extending arms capable ofengaging beneath a horizontal surface or horizontal surfaces provided onthe jar. the joint between the lid and jar being made by means of asuitable packing ring interposed between the two.

The invention may be said to consist essentially in constructing the lidand flexible member so that the latter is capable of be- 'ing depressedat its central part relatively to the lid in such a manner as to causeone or both of the downwardly-extending arms to swing outward clear ofthe above-named surface or surfaces to enable the lid to be readilydetached from and applied to the ar.

For convenience the term jar is hereinafter used for denoting any vesseladapted to be closed by a lid, cover, or stopper, whatever may be theshape or construction of the vessel.

The invention will be best understood by reference to the accompanyingdrawings in which Figure 1 is a central vertical section of a jar andlid, with the improved fastening device, this view showing the lidlocked down to the jar; Fig. 2 is a plan of the lid detached from thejar and with the fastening clip removed therefrom; Fig. 3 is aperspective view of the clip detached, and Fig.

4 is a side elevation of a modified form of the clip.

The jar 1 and the lid 2 may be made of pottery ware. The former isprovided with a flange 3 by forming it with an-annular recess 4. Thejoint between the lid 2 and jar 1 is conveniently made by a rubber orequivalent packing ring or washer 5 encircling the central disk-shapedprojection of the lid, which enters the mouth of the jar.

Specification of Letters Patent.

Patented Nov. 14 1916.

Application filed April 11, 1912. Serial No. 690,061.

Anannular groove 13. is formed in the underside of the flange 3, and theupturned tip or toe of the projection 12 is inserted into the groove 13,while-the projection 11 simply engages beneath the surface of the flange3 at a point diametrically opposite the projection 12. The annularrecess 4 with its annular groove 13 may, however, be non-existent,except at those two diametrically opposite parts where its presence isnecessary for engaging the projections 11 and 12 of the springs: 2'. e.,it may be represented merely by two opposite recesses, each providedwith a small groove or dent in the horizontal surface bounding the saidrecess on its upper side.

To, remove the lid or cover 2, the central portion of the blade spring 8is depressed into the central recess 6, and. the flexing of the saidspring causes the arm 9 which carries the projection 11 to swing outwardapproximately about the point at which such arm joins the spring 8, andas soon as the projection 11 is clear of the horizontal surface of therecess 4:, the lid or cover can be readily turned upward, the projection12 acting as a hinge or pivot by reason of the engagement of itsupturned tip with the groove 13 as aforesaid and as will be apparentfrom Fig. 1. The application and fastening of the lid or cover 2 takeplace by a reverse operation, the toe of the projection 12 being engagedwith its groove 13, while the said lid is in an inclined position, andthe lid being then turned down to the closed position in which theprojection 11, after springing over the peripheral edge of the top ofthe jar, engages the horizontal surface of the diametrically oppositepart of the annular recess 4: as will now be well understood.

The blade spring clip 8 may be made in two parts hinged together at 14as shown in Fig. 4; the manner of fixing the lid 2 (provided with thistwo-part clip) to, and rethe same as that herein before described andtherefore calls for no special explanation.

If desired the upturned part of the tip or toe 12 and the groove 13 maybe dispensed with, both of the arms 9 and 10 of this arrangement beingprovided with similar inwardly-turned projections such as 11.

I claim 7 In combination with an open ended container formed withannular recess so as to leave a flange near its mouth, the flange beingprovided with recesses in its under surface, packing disposed on theupper end of the container, a cover disposed on the packing and providedwith a central depression and a diametrical slot, and a resilientsecuring member disposed in the slot and provided with depending ends,one of which ends is formed with an inwardly projecting lateralextension to engage under the flange of the container and the other ofwhich ends is provided with a lateral extension terminating in anupwardly projecting toe arranged to engage in the adjacent recess in theflange of the container.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
